A really bad online Texas Hold'em poker player; much worse than a fish/whale or a donkey.

A pajama puker tends to tilt extremely easily and then leak all their chips away. They are active in chat rooms at the online poker tables and will often put themselves on tilt when you ignore them.
I couldn't resist playing a while longer with that pajama puker on my right playing every hand.
